Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane foam production, in particular to a polyurethane foam rolling device. Background Art

[0002] Polyurethane sponge is a low-density PU with a foam density below 18kg / m3. The method is usually to use more than 4.5 parts of water (per 100 parts of polyol) and more than 55 parts of TDI. The heat dissipation problem of the foam is very prominent. Since the heat inside the foam is not easy to dissipate, the temperature automatically rises to more than 180°C during the foaming process, which will cause the foam to spontaneously combust.

[0003] During the production of polyurethane foam, the production steps are raw material screening, mixing, processing and final molding and winding. During the final winding, a winding machine is required to wind the molded foam. However, when winding, the traditional winding equipment wraps the wound foam inside the winding equipment. When winding foams of different sizes, there is no limiting mechanism, which leads to the problem of inconvenience in foam winding. Now, there is an urgent need to provide a winding equipment with an adjustable limiting mechanism to wind the foam. Utility Model Content

[0029] Among them, a limit component 2 is provided at one end of the base 1 away from the winding disk 4, and a slide groove 7 is opened at the intersection of the base 1 and the limit component 2. The position of the limit component 2 inside the slide groove 7 is changed to adjust the distance between the limit components 2 at both ends. A limit component 2 is provided at one end of the winding disk 4 above the base 1, and a slide groove 7 is opened at the intersection of the base 1 and the limit component 2. The limit component 2 is slidably connected with the slide groove 7. When rolling up foams of different sizes, the distance between the limit components 2 at both ends can be adjusted by changing the position relationship between the limit components 2 and the slide groove 7 at both ends. For foam limiting, it can be suitable for foams of different sizes. At the same time, the limit component 2 includes a rotating roller 23 and a fastener 22. The foam is in contact with the rotating roller 23. The rotating roller 23 rotates to reduce the friction with the foam. When the slider 21 and the slide groove 7 change position, the slider 21 is tightly connected to the slide groove 7 through the fastener 22.

[0030] The limiting component 2 includes a slider 21 slidably connected to the slide groove 7, a rotating roller 23 is provided at the top of the slider 21, and the rotating roller 23 and the slider 21 are rotatable structures. When the foam contacts the rotating roller 23, the friction between the foam and the foam is reduced by the rotating rotating roller 23 when the foam is rolled up. The slider 21 is located on one side of the rotating roller 23 and is provided with a limiting member 22. The limiting member 22 penetrates the slider 21. When changing the spacing between the two limiting components 2, the limiting member 22 and the slide groove 7 are loosened, and then the slider 21 is pushed to move inside the slide groove 7. When the slider 21 moves to a suitable position, the limiting member 22 is tightened, so that the limiting component 2 and the slide groove 7 are tightly connected.

[0031] By adopting the above technical solution:

[0039] By adopting the above technical solution:

[0040] When the foam is rolled up, the transmission component 5 runs, and the internal motor drives the winding disk 4 to rotate, and the operating speed of the motor can be changed by the frequency converter. The foam moves from the inside of the pressure roller 61, and the pressure roller 61 is a rotatable structure, so that when the foam moves, it drives the pressure roller 61 to rotate, reducing the friction force between the pressure roller 61 and the foam, and when the height of the adjustment component 6 needs to be changed, the connecting piece 64 is loosened at this time so that the connecting piece 64 does not contact the support plate 62, and then the positional relationship between the support plate 62 and the support plate 65 is changed.
